What european power established a government to rule over venezuela and colombia in bogotá?

Spain. It established the Viceroyalty of New Granada in there.

Explanation:

The viceroyalty of New Granada was a Spanish viceroyalty in South America, which included the present-day states of Venezuela, Colombia, Panama and Ecuador. It was formed from parts of the already existing Spanish viceroys New Spain and Peru and was thus the third Spanish viceroyalty on American soil. The establishment of another viceroyalty became necessary after the administration of the vast areas under Spanish rule had proven increasingly difficult in a single viceroyalty.
